I need to create a rule on Drupal Commerce that allow the customers to pay the total amount of the order or just a make partial payment (setup the payment of 20 or 30% of the total amount). This 2 options must be available for the client to choose wich one will he select.

I'm using just 1 payment mode Sermepa Commerce.
